Abstract
Description
Technical Field
[0001] This invention relates to the field of vial opening technology, specifically a medical vial opener capable of batch opening. Background Technology
[0002] For the use of vials ( Figure 1 As shown, when preparing medications, the plastic cap 12 on the vial needs to be removed first to expose the rubber stopper 11 inside the vial opening. Then, a syringe is inserted through the rubber stopper 11 to draw out the medication or inject other medications. Currently, hospitals mainly use the following methods to remove the plastic cap 12 from vials:
[0003] 1. The medical staff held the vial with one hand and used the web of their other hand to pry off the plastic cap 11.
[0004] 2. Use a bottle opener (similar to a beer bottle opener) to open the bottle.
[0005] The above solution has the following problems in practical application:
[0006] 1. The above method can only open one bottle at a time, which is inefficient. Hospitals prepare a large number of medications every day. One dose of medication requires multiple medications to be prepared. Each medication is stored in a vial. Therefore, hospitals need to open a large number of vials every day, and opening one vial at a time is inefficient.
[0007] 2. The large amount of bottle opening work significantly increases the workload of medical staff;
[0008] 3. Method 1 will cause repeated friction between the hands and the skin of medical staff, resulting in hand abrasions. Although Method 2 uses a bottle opener, the repeated operation over a long period of time and the friction between the hand holding the bottle opener and the bottle opener will also cause abrasions. Summary of the Invention
[0009] The present invention aims to provide a medical bottle opener capable of opening bottles in batches, in order to solve the problem of low efficiency of the bottle opening methods mentioned in the background art.
[0010] To achieve the above objectives, the present invention provides the following technical solution:
[0011] A medical bottle opener for batch opening includes an operating table and a cover plate. The cover plate is hinged to the rear side of the operating table. Several placement slots are formed along the front-back direction on the operating table. Vials are placed in the placement slots with their heads facing forward. Clamping components for holding the vials are provided in the placement slots. The cover plate can press the vials tightly when it is closed. A guide rail is fixed below the placement slots along the front-back direction. The guide rail includes a horizontal section and an upwardly extending arc-shaped section. The arc-shaped section is connected to the front end of the horizontal section. A cap-removing plate is slidably connected to the guide rail. The cap-removing plate is connected to a driving component. The top of the cap-removing plate extends into the placement slot. A sliding hole is formed in the placement slot for the cap-removing plate to slide. When the vials are placed in the placement slots, the cap-removing plate can contact the rear end of the plastic cap of the vials.
[0012] The principle of this scheme is as follows:
[0013] The vial is placed in the placement slot with the head facing forward and is held in place by the clamping device. After placement, the cap removal plate is positioned from below against the rear end of the vial's plastic cap. The cap plate is closed, and the drive unit is activated to move the cap removal plate forward quickly along the guide rail, thus removing the plastic cap from the vial and opening the vial.
[0014] The beneficial effects of this plan are:
[0015] 1. The drive unit moves the cap-removing plate forward, which can remove the caps of multiple vials at once, thus opening multiple vials with high efficiency.
[0016] 2. Due to the thinness of the plastic cap, in order to prevent the cap removal plate from sliding over the plastic cap when moving forward, thus making it impossible to remove the plastic cap, this solution divides the guide rail into a horizontal section and an arc section. The arc section extends upward, and when the cap removal plate moves along the arc section, it can complete a forward and upward hooking action, thereby ensuring contact with the plastic cap and ensuring that the plastic cap is removed.
[0017] Furthermore, a cap-removing blade is fixed to the front side of the top of the cap-removing plate, and the free end of the cap-removing blade can contact the plastic cap of the vial.
[0018] In this solution, the free end of the cap-removing blade is used to press against the plastic cap, which concentrates stress and further ensures the removal of the plastic cap, preventing the cap-removing plate from sliding over the plastic cap.
[0019] Furthermore, a bevel is provided on the rear side of the top of the cap removal plate, and the high end of the bevel is connected to the top of the cap removal plate, allowing the bevel to contact the body of the vial.
[0020] Since the vial is held by a clamping device, there is a certain friction when it is removed. This solution drives the cap removal plate to move in the opposite direction until the inclined surface contacts the vial. The inclined surface is used to lift the head of the vial from the placement slot, making it easier to remove the vial from the placement slot later.
[0021] Furthermore, the drive unit is electrically connected to a controller, the controller is electrically connected to a sensor, the sensor is located on the front side of the operating table, and the guide rail is provided with a capping position located in front of the initial position of the capping plate and a bottle lifting position located behind it. The bottle lifting position is located at the body of the vial.
[0022] After the sensor detects that the cover has been closed, it sends a cover rejection signal to the controller.
[0023] The controller controls the drive unit to move the cap-removing plate to the front of the operating table to the cap-removing position based on the cap-removing signal;
[0024] Once the sensor detects that the lid has left, it sends a bottle-lifting signal to the controller.
[0025] The controller controls the drive unit based on the bottle lifting signal to move the cap removal plate to the rear of the operating table to the bottle lifting position. After an interval of 2-4 seconds, the controller controls the drive unit to move back to the front of the operating table to return to the initial position.
[0026] Using this solution, the bottle can be opened automatically when the cap is closed, and after the cap is opened, the bottle can be opened automatically by driving the bottle to move in the opposite direction to lift the vial. After being lifted, the bottle can be automatically reset, which has a high degree of automation and further improves efficiency.
[0027] Furthermore, the clamping component is an airbag with a U-shaped cross-section. The airbag is fixed to the inner wall of the placement groove and is connected to an inflation mechanism. The airbag is located on the rear side of the sliding hole.
[0028] 1. An airbag is designed as a clamping component. By controlling the inflation volume of the airbag, its volume can be adjusted to accommodate various sizes of vials. 2. In practical application, the height of the cap-removing plate should be such that the plastic cap of the largest vial placed in the placement slot is abutted against the plate. When a smaller vial is placed in the placement slot, its head is supported at a certain height by the cap-removing plate, but the body is too small to abut against the bottom of the placement slot. In this case, the inflation volume of the airbag can be increased. Because a U-shaped airbag is used, it can fill the gap between the bottom of the vial and the placement slot, allowing the smaller vial to fit comfortably. It can also clamp the smaller vial from both sides, thus securing it. In summary, by adjusting the inflation volume of the airbag, it can accommodate various sizes of vials, expanding its applicability.
[0029] Furthermore, a collection chamber is provided on the front side of the placement slot, and a collection drawer is slidably installed inside the collection chamber, with a handle fixed on the collection drawer.
[0030] The removed plastic caps fall into the collection drawer to prevent them from scattering everywhere; simply pull out the collection drawer to dispose of the plastic caps inside, making the process convenient. Attached Figure Description

[0037] The following detailed description illustrates the specific implementation method:
[0038] The reference numerals in the accompanying drawings include: vial 1, rubber stopper 11, plastic cap 12, operating table 2, cover plate 3, sensor 31, placement slot 4, airbag 41, sliding hole 5, cap-removing plate 51, cap-removing blade 52, bevel 53, driving component 54, connecting plate 55, strip hole 56, horizontal section 57, arc section 58, baffle 6, collection chamber 61, collection drawer 62, cap-removing position A, bottle-lifting position B.
[0039] Example 1:
[0040] like Figure 2 As shown, a medical bottle opener capable of batch opening includes an operating table 2 and a cover plate 3. The cover plate 3 is hinged to the rear side of the operating table 2. Several placement slots 4 for placing vials 1 are formed along the front-back direction on the operating table 2. Only seven placement slots 4 are shown in this embodiment; the actual number of slots 4 can be adjusted as needed. The cover plate 3 can press the vials 1 firmly when closed. Clamping components (not shown in the figure) for holding the vials 1 are provided inside the placement slots 4. In this embodiment, the clamping components are rubber pads, which are glued to the inner walls on both sides of the placement slots 4. A collection cavity 61 is formed on the front side of the placement slots 4. A collection drawer 62 is slidably installed in the collection cavity 61. A handle (not shown in the figure) is bolted to the collection drawer 62, allowing it to be pulled out of the collection cavity 61. A baffle 6 is vertically fixed to the front side of the collection cavity 61 by bolts. The length of the cover plate 3 is less than the length from the baffle 6 to the rear side of the operating table 2.
[0041] Combination Figure 3As shown, each placement slot 4 has a guide rail installed along the front-to-back direction below it. The rear end of the guide rail is fixed to the operating table 2 by bolts. The guide rail includes a horizontal section 57 and an upwardly extending arc-shaped section 58. The arc-shaped section 58 is integrally formed at the front end of the horizontal section 57. Each guide rail is slidably connected to a cap-removing plate 51. The top of the cap-removing plate 51 extends into the corresponding placement slot 4 above it. The placement slot 4 has a sliding hole 5 for the cap-removing plate 51 to slide. When the vial 1 is placed in the placement slot 4, the cap-removing plate 51 can contact the rear end of the plastic cap 12 of the vial 1. The sliding hole 5 is provided with limit protrusions (not shown in the figure) on both sides of the vial 1 shoulder (the connection between the bottle body and the neck) to increase the stability of the vial when opening the cap. The cap-removing plate 51 is connected to a driving component 54, which is a cylinder. Specifically, in conjunction with Figure 4 As shown, the rear end of each cover plate 51 is connected to the same connecting plate 55. A strip hole 56 is opened on the rear side of the connecting plate 55. A connecting rod is slidably connected in the strip hole 56. The connecting rod is fixed to the piston rod of the cylinder by bolts.
[0042] The top front side of the cap removal plate 51 is integrally formed with a cap removal blade 52. The free end of the cap removal blade 52 can contact the plastic cap 12 of the vial 1. The top rear side of the cap removal plate 51 is cut with a bevel 53. The high end of the bevel 53 is connected to the top of the cap removal plate 51. The bevel 53 can contact the body of the vial 1.
[0043] Combination Figure 5 As shown, the drive unit 54 is electrically connected to a controller, which is a PLC. The controller is electrically connected to a sensor 31 and an indicator light. The sensor 31 is a proximity switch or an infrared sensor, mounted on the front surface of the operating table 2. The guide rail has a cap-removing position A located in front of the initial position of the cap-removing plate 51 and a bottle-lifting position B located behind it. Bottle-lifting position B is located at the body of the vial 1. When the sensor 31 senses the cap 3 being closed, it sends a cap-removing signal to the controller. Based on the cap-removing signal, the controller controls the drive unit 54 to move the cap-removing plate 51 towards the front of the operating table 2 to cap-removing position A. When the sensor 31 senses the cap 3 being removed, it sends a bottle-lifting signal to the controller. Based on the bottle-lifting signal, the controller controls the drive unit 54 to move the cap-removing plate 51 towards the rear of the operating table 2 to bottle-lifting position B. After a 2-second interval, the controller controls the drive unit 54 to move back to the initial position. In practical application, by presetting the stroke of the drive unit 54 and the aforementioned intervals in the controller, the cylinder's action can be automatically controlled.
[0044] In use, the operator places vial 1 head-first into placement slot 4, so that the rear end of plastic cap 12 of vial 1 abuts against cap-removing blade 52. Figure 3 As shown in the diagram, after being placed in the vial, the vial 1 is fixed in the placement slot 4 by the clamping device.
[0045] The operator closes the cover plate 3. After the sensor 31 detects the cover plate 3, it sends a rejection signal to the controller. Based on the rejection signal, the controller controls the drive unit 54 to drive the rejection plate 51 to move forward quickly along the guide rail. Figure 2 The device moves from the left side to the cap removal position A, thereby removing the plastic cap 12 from the vial 1. At this time, the controller indicator light illuminates, and the removed plastic cap 12 falls into the collection drawer 62 for collection. The baffle 6 ensures that the plastic cap 12 falls into the collection drawer 62.
[0046] Since the plastic cap 12 is relatively thin, in order to prevent the cap removal plate 51 from sliding over the plastic cap 12 (i.e. missing the plastic cap 12) and failing to remove the plastic cap 12 when it moves, this embodiment has a cap removal blade 52 integrally formed at the top of the cap removal plate 51. When pushing, the stress can be concentrated on the plastic cap 12 through the cap removal blade 52. In addition, the cap removal plate 51 moves forward and upward along the arc section 58 of the guide rail, so it can avoid the situation where the cap removal plate 51 slides directly over the plastic cap 12 and fails to remove the plastic cap 12, thus ensuring the removal effect.
[0047] After the indicator light illuminates, the operator opens the cover plate 3. Sensor 31 detects the opening and sends a bottle-lifting signal to the controller. Based on this signal, the controller controls the drive unit 54 to move the cap-removing plate 51 in the reverse direction to the bottle-lifting position B. The inclined surface 53 on the cap-removing plate 51 abuts against the body of the vial 1, lifting the head of the vial 1 upwards for subsequent removal from the placement slot 4. Two seconds after the cap-removing plate 51 reaches the bottle-lifting position, the controller controls the drive unit 54 to reset the cap-removing plate 51 to its initial position, at which point the operator can remove the vial 1. This completes the opening of a batch of vials 1.
[0048] Example 2:
[0049] like Figure 6 As shown, the difference between this embodiment and embodiment one is that the clamping component is an airbag 41, the cross-section of the airbag 41 is U-shaped, the airbag 41 is glued and fixed to the inner wall of the placement groove 4 on the rear side of the sliding hole 5, and the airbag 41 is connected to an inflation mechanism, which is an air pump.
[0050] This embodiment is applicable to various sizes of vials 1. During design, the height of the cap-removing plate 51 is such that the largest vial 1 among the applicable vials 1, when placed in the placement slot 4, abuts against the top of the cap-removing plate 51. The inflation volume of the air bladder 41 is also designed so that the vial 1 is held in place by the air bladder when horizontally placed in the placement slot 4. When a smaller vial 1 is placed, the plastic cap 12 of the vial 1 abuts against the cap-removing plate 51, but a gap remains between the vial body and the air bladder 41. By increasing the inflation volume of the U-shaped air bladder 41, the gap at the bottom of the vial body can be filled, and the vial 1 can be clamped from both sides, thus securing the smaller vial 1. In summary, this embodiment is applicable to securing vials 1 of various sizes, and has a wide range of applications.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
